Abstract
L'INVENTION EST RELATIVE A UN PALIER D'ARBRE CONTENANT DEUX ENSEMBLES DE BILLES. POUR FACILITER LE MONTAGE ON PREVOIT DES CAGES 12, 13 DONT LES LOGEMENTS DE BILLES SONT ELASTIQUES ET MAINTIENNENT LES BILLES 4, 5, MEME LORS DES VARIATIONS DE DIAMETRE DE L'ARBRE 1. CES CAGES ONT UNE SECTION EN T AVEC DES AILES 12, 12 QUI VIENNENT EN APPUI SUR UN EPAULEMENT 1 DE L'ARBRE OU SUR UNE FACE FRONTALE D'UNE BAGUE EXTERIEURE 6, 7, DE FACON A ASSURER A LA FOIS LA MISE EN PLACE CORRECTE DES BILLES DANS LEUR CHEMIN DE ROULEMENT 2 ET L'ETANCHEITE. UNE ENTRETOISE TUBULAIRE 8 MUNIE D'UN RESSORT 10 MAINTIENT LA POSITION RELATIVE DES BAGUES 6, 7 MAIS PERMET LEUR DEPLACEMENT POUR LE MONTAGE.THE INVENTION RELATES TO A SHAFT BEARING CONTAINING TWO ASSEMBLIES OF BALLS. TO FACILITATE THE ASSEMBLY, CAGES 12, 13 ARE PROVIDED, THE BALL HOUSINGS OF WHICH ARE ELASTIC AND KEEP THE BALLS 4, 5, EVEN WHEN THE DIAMETER VARIATIONS OF SHAFT 1. THESE CAGES HAVE A T-SECTION WITH WINGS 12, 12 WHICH COME IN SUPPORT ON A SHOULDER 1 OF THE SHAFT OR ON A FRONT FACE OF AN EXTERNAL BUSH 6, 7, SO AS TO ENSURE BOTH THE CORRECT PLACEMENT OF THE BALLS IN THEIR BEARING TRACK 2 AND THE WATERPROOFING. A TUBULAR SPACER 8 EQUIPPED WITH A SPRING 10 MAINTAINS THE RELATIVE POSITION OF BUSHES 6, 7 BUT ALLOWS THEIR MOVEMENT FOR ASSEMBLY.

Des paliers de ce type ont été décrits dans le document DE-A-3 231 138. Le montage de ces roulements, en particulier celui du dernier palier est difficile, même si, Bearings of this type have been described in document DE-A-3,231,138. The mounting of these bearings, in particular that of the last bearing, is difficult, even if,

Même si celle-ci est pourvue de saillies d'arrêt pour empêcher les billes de s'échapper pendant le montage, l'introduction de ces billes est difficile: il faut les introduire à force une à une dans leur logement The upper part can be axially offset during the introduction of the balls and the cage. A so-called "window" cage finds its use here. Even if it is provided with stop protrusions to prevent the balls from escaping during assembly, the introduction of these balls is difficult: it is necessary to force them one by one into their housing.

Du fait que les billes sont bien maintenues dans la cage à peigne à la fois dans le sens radial et le sens axial, on peut obtenir dès avant le montage un ensemble Because the balls are well held in the comb cage both radially and axially, it is possible to obtain a set before assembly.

ge à section en T vient rencontrer l'épaulement de l'arbre ou bien la bague extérieure, ce qui immobilise ladite cage. Les billes ne peuvent alors pas aller plus loin et heurter lbord du chemin de roulement prévu dans l'arbre; grâce aux parties élastiques des logements de la cage, elles sont sensiblement centrées dans leur chemin de roulement, et ne risquent pas d'être endommagées. Un tel incident ne peut pas non plus se produire lors du recul de la bague extérieure, car les billes sont déjà maintenues correctement par la cage dans le chemin de roulement prévu T-section section meets the shoulder of the shaft or the outer ring, which immobilizes said cage. The balls can not then go further and hit the lane of the planned race in the tree; thanks to the elastic parts of the housing of the cage, they are substantially centered in their raceway, and are not likely to be damaged. Such an incident can not occur either during the retraction of the outer ring, because the balls are already held correctly by the cage in the planned raceway

La section en T de la cage procure en outre une étanchéité au palier, car, après montage, il ne subsiste qu'un jeu très faible entre les ailes de la cage d'une The T-section of the cage also provides a seal at the bearing because, after assembly, there remains only a very small clearance between the wings of the cage of a

En outre, du fait que ce passage est rempli de lubrifiant, on empêche l'oxydation de la face frontale de la bague extérieure, dont l'effet inesthétique If the wings of the cage go radially substantially to the shaft on one side and to the outer diameter of the outer ring on the other side, the labyrinth passage is further extended. In addition, because this passage is filled with lubricant, it prevents the oxidation of the front face of the outer ring, the unaesthetic effect
